【问题描述】:
您好,我正在编写 Chrome 离线扩展程序。我知道我不能包含 JS 内联。这段代码来自一个 jquery 小部件,它可以在浏览器上完美运行……但在应用程序中却不行。我猜这与$.widget("custom.combobox", {_create: function() {},_createAutocomplete: function() {}, ... );有关
我在一个不起作用的小部件的其他文件中遇到了类似的问题。检查一个小时后,我删除了这行代码$( "#tags" ).autocomplete({ minLength: 0, source: availableTagsForFiles });(在浏览器上完美运行)并再次运行。
我正在使用谷歌浏览器来处理所有事情。
我认为如果我以不同的方式写这个$.widget("custom.combobox", {_create: function() {},_createAutocomplete: function() {}, ... ); 会更正。但我不知道 jquery 足以做到这一点。 (这只是一个假设)。有人可以帮我吗?
不工作的脚本:
$(文档).ready(函数($){
console.log("再见,残酷的世界!");
$.widget("custom.combobox", {
_创建:函数(){
this.wrapper = $( "" )
.addClass("自定义组合框")
.insertAfter(this.element);
this.element.hide();
this._createAutocomplete();
this._createShowAllButton();
},
_createAutocomplete: function() {
var selected = this.element.children( ":selected" ),
value = selected.val() ? selected.text() : "";
this.input = $( "<input>" )
.appendTo( this.wrapper )
.val( value )
.attr( "title", "" )
.attr( "id", "EscribeCssTextbox" )
.addClass( "custom-combobox-input ui-widget ui-widget-content ui-state-default ui-corner-left" )
.focus(cargaTodosLosIdsClasesYElementos)
.keyup(ocupaCambio)
.autocomplete({
delay: 0,
minLength: 0,
source: $.proxy( this, "_source" )
})
.tooltip({
tooltipClass: "ui-state-highlight"
});
this._on( this.input, {
autocompleteselect: function( event, ui ) {
ui.item.option.selected = true;
this._trigger( "select", event, {
item: ui.item.option
});
},
autocompletechange: "_removeIfInvalid"
});
},
_createShowAllButton: function() {
var input = this.input,
wasOpen = false;
$( "<a>" )
.attr( "tabIndex", -1 )
.attr( "title", "Show All Items" )
.tooltip()
.appendTo( this.wrapper )
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass( "ui-corner-all" )
.addClass( "custom-combobox-toggle ui-corner-right" )
.mousedown(function() {
wasOpen = input.autocomplete( "widget" ).is( ":visible" );
})
.click(function() {
input.focus();
// Close if already visible
if ( wasOpen ) {
return;
}
// Pass empty string as value to search for, displaying all results
input.autocomplete( "search", "" );
});
},
_source: function( request, response ) {
var matcher = new RegExp( $.ui.autocomplete.escapeRegex(request.term), "i" );
response( this.element.children( "option" ).map(function() {
var text = $( this ).text();
if ( this.value && ( !request.term || matcher.test(text) ) )
return {
label: text,
value: text,
option: this
};
}) );
},
_removeIfInvalid: function( event, ui ) {
// Selected an item, nothing to do
if ( ui.item ) {
return;
}
// Search for a match (case-insensitive)
var value = this.input.val(),
valueLowerCase = value.toLowerCase(),
valid = false;
this.element.children( "option" ).each(function() {
if ( $( this ).text().toLowerCase() === valueLowerCase ) {
this.selected = valid = true;
return false;
}
});
// Found a match, nothing to do
if ( valid ) {
return;
}
// Remove invalid value
this.input
.val( "" )
.attr( "title", value + " didn't match any item" )
.tooltip( "open" );
this.element.val( "" );
this._delay(function() {
this.input.tooltip( "close" ).attr( "title", "" );
}, 2500 );
this.input.data( "ui-autocomplete" ).term = "";
},
_destroy: function() {
this.wrapper.remove();
this.element.show();
}
});
});
$(document).ready(function() {
console.log("BUAAAAAAAAAAA I'LL cry !!");
$( "#combobox" ).combobox();
$( "#toggle" ).click(function() {
$( "#combobox" ).toggle();
});
});
